This is the second time Nelbud cleaned our hoods. The first one was nasty I reported this because the left the whole Back of the house dirty while the hood filters were clean but the walls the panels opposite the hood filters were all oily. Today, I checked what they have done, the Back of the house floors were ok but the walls were still all oily and the panel opposite the hood filters were literally dripping oil. They also did not throw away the trash where they used when cleaning. What is the standard output of the cleaners?
